Then, I read some articles that said I needed to install /opencl_runtime_16.1.1_x64_sles_6.4.0.25.tgz
and /intel_sdk_for_opencl_2016_6.3.0.1904_x64.tgz but when I tried to run them I got:

Based on contents availability and coexistence checks, there is nothing to
install from this package. Installation will quit.
So, that's when I decided to ask for help. I am stuck.
Thank you for your time.
